Definitions
- the present disclosure relates to a method and an apparatus for recovering fibers embedded in a composite material, the apparatus comprising a furnace chamber for thermolyzing a volume of the composite material, which is a step of the method.
- a composite material is a material made from two or more components (constituent materials) with different physical or chemical properties that, when combined, produce a material (the composite) with characteristics different from the individual components and superior thereto.
- the individual components enhance each other but remain separate and distinct within the composite.
- the matrix material surrounds and supports the reinforcement materials by maintaining their relative positions, and bestows thermal and environmental resistance upon the composite.
- the reinforcements impart their special mechanical and physical properties to strengthen the matrix, for instance to prevent crack propagation.
- Polymers are typical matrices especially used for fiber-reinforced plastics, wherein the fibers constitute the reinforcement.
- Most common polymer-based composite materials comprise a resin, e.g. epoxy resin.
- resins used for these composites include polyester and epoxy, while glass and carbon fibers are often employed as reinforcement.
- EP2783764 discloses a method consisting in a thermal process in which the composite material is pyrolyzed at a relatively low temperature in a closed furnace chamber with an inactive atmosphere, for example in the form of nitrogen.
- the temperature and combustion conditions are intended for the matrix to be gasified while leaving the fibers more or less intact, thus making recycling possible, at least in principle.
- a method for recovering fibers embedded in a composite material comprises the steps of: loading a furnace chamber (for example, a first furnace chamber, anticipating the possibility of further furnace chambers but without precluding a single furnace chamber) with a volume of the composite material; thermolyzing the composite material in said furnace chamber, resulting in gaseous fraction that is continuously evacuated from the furnace chamber, and a residue of fibers covered with char that is left in the furnace chamber; cracking the gaseous fraction from the thermolysis step, resulting in a mixture of condensable and non-condensable gases; injecting a stream of an oxygen-containing gas into the still hot furnace chamber after the thermolysis is completed therein, in order to burn the char from the fibers in an exothermic combustion.
- a furnace chamber for example, a first furnace chamber, anticipating the possibility of further furnace chambers but without precluding a single furnace chamber
- thermolyzing the composite material in said furnace chamber resulting in gaseous fraction that is continuously evacuated from the furnace chamber, and a
- thermolysis is herein used to encompass the splitting of complex molecules into simpler ones under the influence of heat and catalysts.
- the cracking of the thermolysis gases into condensable and non-condensable gases is an useful way to treat the gaseous residues from the thermolysis because the condensable gases can, for example, be condensed and used as fuel.
- thermolysis may be a pyrolysis, i.e. a thermolysis in the absence of oxygen (or any halogen).
- the thermolysis or the pyrolysis may be performed under vacuum in order to speed it up, for example at 0.1-0.9 bars.
- the oxygen-containing gas may contain O 2 and/or O 3 (ozone).
- O 2 and/or O 3 ozone
- the use of ozone may speed up the exothermic combustion.
- the oxygen-containing gas may be air enriched with 2-20% in volume of oxygen.
- the loading of the furnace chamber may be done by means of a cage that can be filled with the composite material outside the chamber and can be loaded into the chamber very quickly, whereby the aperture time of furnace chamber would be shortened (or even minimized), which would improve the energy efficiency of the process.
- the method further comprises the step of using the non-condensable gases for contributing heat to the furnace chamber in the thermolysis or pyrolysis step, thus improving the energy efficiency of the process.
- the non-condensable gases may be used for cogeneration, which also improves the overall energy efficiency.
- the cracking step may be performed by circulating the gaseous fraction through a reducing agent, particularly through a catalyst, like for example SiC or zeolite.
- two furnace chambers might be used, the above-mentioned first furnace chamber and a second furnace chamber, so that the method would further comprise the steps of:
- thermolysis may be a pyrolysis, and the other variants explained above (in relation to one furnace chamber) may also be applied herein (in relation to two furnace chambers).
- an apparatus for recovering fibers embedded in a composite material comprises a furnace chamber for thermolyzing (or pyrolyzing) a volume of the composite material, which can produce the above-mentioned gaseous fraction, and a reducing agent (e.g. a catalyst) for cracking the gaseous fraction, which can produce the above-mentioned mixture of condensable and non-condensable gases.
- a reducing agent e.g. a catalyst
- the heating of the furnace chamber may be carried out, perhaps partially, by means of a gas burner fueled (at least in part) by the non-condensable gases produced in the cracking step.
- a gas burner fueled (at least in part) by the non-condensable gases produced in the cracking step.
- alternative or complementary means to heat the furnace chamber may also be envisaged, such as radiation means, convection means, induction means, micro-wave means, electric resistances, etc.
- the apparatus of figures 1 and 2 comprises a furnace 1 provided with a furnace chamber 10, a burner 11 for the chamber 10, a first outlet 12 from the chamber 10, an inlet 13 to the chamber 10 and a second outlet 14 therefrom.
- the first outlet 12 leads (through a conduit) to a reducing member 20 comprising a reducing agent 21, for example zeolite or a SiC catalyst.
- a condenser 31 Downstream from the catalyst is a condenser 31, from where non-condensable gases can be brought, through a filter 32, to the burner 11.
- the inlet 13 allows to inject a stream of air (or other oxygen-containing gas) into the furnace chamber 10, and the second outlet 14 is to evacuate combustion gases from the furnace chamber 10 to a separator (e.g. a cyclone) 41 and some further filters 42.
- the apparatus also comprises suitable valves in the conduits.
- the operation with the apparatus is as follows (the goal is to extract clean fibers from a discarded part made of a polymer-based composite material with embedded fibers, e.g. glass or carbon fibers, for example a removed wind turbine blade):
- the reducing agent 21 is thermostated, i.e., its temperature is carefully controlled in order to optimize the cracking reactions.
- the non-condensable gas or gases brought into the burner 11 are burned therein and thus contribute thermal energy to the pyrolysis (at the beginning, when this recycled fuel is not available yet, an external fuel can be used, for example propane), or, alternatively, instead of bringing the non-condensable gas to the burner 11, the non-condensable gas can be used to drive a turbine (not shown) in a cogeneration process.
- the condensed gases can be collected in different containers depending on their condensation temperatures.
- FIG. 3 shows the pyrolysis and cracking processes (steps C, D and E).
- the solid black valves represent open valves and the white valves represent closed valves.
- the straight arrows represent gas flows and the curved arrow at the bottom of the condenser 31 would represent a liquid flow (in case the corresponding bottom valve would be open).
- FIG. 4 shows the exothermic combustion (steps F and G); as before, the solid black valves represent open valves and the white valves represent closed valves, and the straight arrows represent gas flows.
- the multi-pointed arrow in chamber 10 represents the char combustion.
- Step F can be termed 'exothermic sweeping'.
- FIG. 5 shows another example in which the furnace 1 comprises two furnace chambers, a first furnace chamber 10 and a second furnace chamber 15.
- This apparatus can be operated in batch mode as follows:
- the weight-ratio of recycled clean fibers to the fibers initially contained in the composite material was estimated to be of approximately 95%, which shows the effectiveness or the method described above.
- the method further produces energy (from the non-condensable gases) and fuel (the condensable gases).
